Pay attention to the maintenance of Baic Car during the winter. Because the temperature is low in winter, some parts of Baic Car are very fragile. Careful protection will delay the life of Baic Car.
What kind of glass water to use in winter needs to be determined according to the temperature of the area where it is used. Generally, glass water at about -15 degrees can be used in central and eastern China in winter, and glass water at -25 degrees can be used in north, northwest, and southwest China. In the cold Northeast region, it is recommended to use -40 degree glass water.
Antifreeze is the main medium for heat dissipation in Petrol Car engines. The antifreeze circulates in large, small, and mixed directions in the engine to complete the engine's heat dissipation. Therefore, antifreeze is very important for the engine. In fact, the engine in the car is very "afraid of heat", but it will become "afraid of cold" in winter, because the coolant may freeze in winter, similar to glass water, which will cause the radiator to burst or freeze. Engine cylinders and heads.
It is responsible for the heat dissipation function of the engine during daily driving, ensuring that the engine can work within the normal temperature range. Whether the antifreeze is normal or not directly affects the performance and service life of the Petrol Car engine.
If you add ordinary water to the antifreeze in summer, you must replace the antifreeze in winter. Replenish insufficient coolant, otherwise the engine water temperature will be too high, causing damage to engine parts. It is generally recommended to replace antifreeze every two years. As for the choice of antifreeze, the lower the freezing point, the stronger the frost resistance.
The battery is also "cold-resistant". The battery capacity of the battery in a low-temperature environment is lower than that at normal temperature. This is determined by the inherent chemical properties of the battery. As far as mainstream batteries are concerned, the electrolyte becomes viscous and even condenses at low temperatures, resulting in slow charging and discharging at low temperatures.
Generally speaking, the optimal temperature of the battery is 25 degrees. Every time it decreases by 1 degree, the available capacity of the battery will decrease by about 0.8%. Once winter arrives, especially in northern areas, the temperature will generally drop to minus 10 degrees Celsius, and the available capacity of the battery will be greatly reduced, which may make it difficult to start an Petrol Car.
In winter, especially in the north, car owners need to turn on the "cold mode" for the battery in advance. Regularly check whether the battery electrodes are loose or corroded; for long-term short-distance vehicles, charge the battery regularly; when starting an Petrol Car, the starting time should not exceed 5 seconds; if it cannot start three times, do not force it to start; if it is used for a long time For batteries, you can go to the nearest after-sales service agency for Petrol Car battery testing.
The engine is the heart of an Petrol Car, and its importance in winter maintenance is self-evident. Lubricating oil is the most important part of engine maintenance. Winter is coming, and the viscosity of general lubricating oil will become very poor due to the drop in temperature, so the friction resistance of parts will increase during movement.
In autumn and winter, the lubricating oil from the fuel tank to the engine must be injected quickly. It is recommended to choose synthetic lubricating oil with low viscosity and good low-temperature fluidity. It can reach every corner of the engine instantly, form an oil film to protect the parts that need lubrication, effectively reduce wear, keep the engine starting smoothly, and have sufficient power output, even at minus 20 to 30 degrees Celsius. It can also provide good protection for the engine at low temperatures.
